Comparison:

Article Title: A Snapshot of the Global Trade of South African Native Vertebrate Species Not Listed on CITES.
Article Snippet: There was a significant difference between the number of species traded as wildlife products and pets (Pearson’s Chi-squared test: χ2 = 153.77, df = 3, p < 0.05).

Article Title: Freshwater genome-reduced bacteria exhibit pervasive episodes of adaptive stasis.
Article Snippet: In contrast, the SPs of species with small genomes are characterised by the near absence of positive selectionpressure and a reduction in the number of genes and sites evolving under negative selection when compared with the CPs (Pearson’s Chi-squared test: χ2 = 44.71, df = 2, P < 0.001; Fig. 5a).

Article Title: Road salt pollution alters sex ratios in emerging mosquito populations.
Article Snippet: De-icing road salt is a persistent emerging pollutant in temperate freshwater systems, where winter salting is necessary for road and pedestrian safety.. Experts argue that road salts may increase salt-tolerant mosquito populations and, potentially, disease transmission in urban areas.. Only adult females consume bloodmeals and may carry zoonotic diseases.

Article Title: Cognitive function in amyotrophic lateral sclerosis: a cross-sectional and prospective pragmatic clinical study with review of the literature.
Article Snippet: Regarding the differences between the three subgroups of ALS, in 24 (96%) individuals with spinal symptoms, normal cognitive performance was detected, 1 3 while normal cognition based on MoCA was observed in seven (58%) participants with bulbar symptoms and in ten (67%) participants with both spinal and bulbar symptoms (Pearson’s Chi-squared test, Χ2 = 8.772, p value = 0.012).

Article Title: Practice pharmacists and their influence on prescribing in UK general practice: a cross-sectional study.
Article Snippet: Parametric analyses (Pearson’s Chi-squared test (χ2)) were conducted to evaluate between-group differences or associations for categorical variables.

Article Title: Benefiting from the past: establishing in vitro culture of European beech (Fagus sylvatica L.) from provenance trial trees and seedlings.
Article Snippet: A comparison of the shoot formation rates after 12 weeks of in vitro culture across the media used in E II and E III demonstrated a significant effect of the media on in vitro shoot formation (Pearson’s chi-squared test, χ2(5) = 13.87, p = 0.016).

Article Title: Effect of Carcass Feeds on Feeding Behavior and Social Interactions in Zoo-Based African Wild Dogs (Lycaon pictus).
Article Snippet: Indeed, treatment affected the proportion of interactions resulting in sharing (Pearson's Chi‐squared test: χ2(2) = 166.82, p< 0.0001).
